Can anyone elaborate on what this is actually looking like in other countries?
I did earlier on in the thread ... in Hong Kong it's shifted on line. In fairness most schools had plans for this after an earlier shut down for protests so it was up and running within days for many schools, all be its evolving over time as teachers, students and parents work out what's working and what's not.
For primary it's a range of preset work through google classroom or various online apps. Most of the kids know how to use these from school. There's sometimes prerecorded videos or a google hangout with teachers (there's various safe guarding put in place like always having an adult present at home when this happens and it being in small groups). But no denying a lot of it falls back on the parents to support - a huge bone of contention on local Facebook pages as you can imagine!
Lower primary is a pain because they have attention spans of gnats but equally if they miss a few weeks at that age it's hardly going to impact their final exams at 16/18. There's a general view, these parents should relax a bit and keep up arts/crafts, basic reading/writing/maths dependent on age. Upper primary kids are generally more self sufficient, and submit work online for marking and feedback. At my kid's school there's a lot of work going on in the background planning to provide support for when the schools reopen to ensure everyone catches up and an assumption that curriculums may need to take this into account next year.
For Secondary they follow the normal timetable, and switch google classroom/ hangout for each subject. The vast majority of secondary students are tech savvy so understand it much better than parents or teachers, in fact in the first week I'd say the the students taught the teachers how to use the tech and some continue to collaborate with students on how best to teach online. DS is forever making videos of himself presenting stuff, students build quizlets to help others, they collaborate on essays online and through FaceTime. Far too much screen time but the teens arent complaining about that.
With few exceptions parents teachers and students can't wait to get back to school.
And to answer a PP yes there's dogs and doorbells, work conference calls and other kids making noise in the background - it's not suppose to be perfect, it's a best we can do in the circumstances.
